Swetman Island

Swetman Island, formerly False Duck Island, is a small Canadian island in Lake Ontario, south of Picton, Ontario.

[3] Nearby Timber Island is also considered part of the False Duck Islands.

The False Duck Islands, the Main Duck Islands, and Galloo Island and Stony Island on the US side, and their associated shoals, form the Duck Galloo Ridge.

The first stone lighthouse on the island was built in 1829.

It was changed to automated operation in 1989.
